Answer:
17.64 m/s
Step-by-step explanation:
The velocity of an object at the end of a given time period can be found using the formula v = gt, where v is the velocity, g is the acceleration due to gravity (9.8 m/s^2 on Earth), and t is the time elapsed.
In this case, we can use the formula to find the velocity of the demon drop ride at the end of 1.8 seconds:
v = gt
= 9.8 m/s^2 * 1.8 s
= 17.64 m/s
Therefore, the velocity of the demon drop ride at the end of 1.8 seconds is approximately 17.64 m/s. This is the velocity the ride will have reached due to the acceleration of gravity pulling it downward.
